To all whom i! may concern.'

Be it known that I, Fimo I. GETTY, e citizen of the United States,residing et Jennings, in the parish of Celciisieu und Stute ofLouisiane, have invented certain new end useful Improvements in Machinesfor Menufncturing bcreenings for Well- `ubes, of which the following isn s ieciiicetion.

`My invention relates to cert-nin new und useful improvements inmachines for menufncturing screening for well tubes und its object is toproduce n device off this class which shell have certain advantageswhich will appear more fully and et large in the course of .thisspecificntion.

To this ond, my invention consists in the Anovel-features which nreshown in the eccompanying drawings es embodied in my preferred form ofconstruction..

In the aforesaid drnwingsF1gure 1 1s en elevation of iny improveddevice, showing the saine in use; Fig. 2 is a face view of the bracketwhich holds the wire-guide in en upright position; Fig. 3 is a sectionin the line 3--3 of Fig. 4, through the wire-guide; Fig. 4 is n sectionin the line 44 of Fig. 1, looking in the direction, of the arrow; Fig.'is e top plan of the screen-forming mechanism; Fig. 6 is e front viewof the seme; Fig. 7 is n horizontal Section in the line 7 7* of Fig. 4;Fig, 8 is e rear elevation of the mechanism; Fig. 9 isn section in theline 9-9 of Fig. 5;

10 is a. )erspcctivc view of the'suppi'irting frame; ig. 11 is a sectionin the line 11--11 of Fig, l; looking in the direction of the arrow;Fig. '12 is en elevation of the forming rolls, looking from the left inFig. 5 Fig. 13 isn horizontal section in the line 13-,13 of Fig. 12; undFig. 14 is a perspective view of the shifting shoe.

The type of screen which iny improved device isdesigned to forni is thatwherein n wire having suitably-spaced lugs is wound around nl perforatedpipe. ln practice, n long length of pipeis provided with perform tionsof the proper size and is wound with wire from end to end. The pi e thusprepared may be joined by suiteb e couplings, so es to produce anydesired length.

Referring now to the drawings, A, indiestes the pipe which is used, thesinne having n plurality of perforetions, a, and being ron tntnblymounted in n. inthe, B, of the ordineryiorm. Thilo I prefer to use .anordi- ,nary machine lathe, it will -be obvious that any device by whichthe pipe een he symmetricall and rotntebly journnled will'opersite equaly es well. ln the use of my irnproved device, u freine, C, is mounted.di rectly upon the pipe itself, the seid freine being yieldingly pressedtoward the left, es viewed -in Fig. 1, by ineens of n. weight, C,

connected with the freine by e cord, c, run.

ningr over pulleys, c2. The frame C, has e rearwardlyprojeating nrni,C2, which rests upon s rod, b, secured to the inthe-bed, seid rodoperating to-limit the backward rotation of the freine as the.pipe-is-roteted. In other words, the rod by engaging with the erin, C2,preyents the frame from rotating, und muses it tb remain stationery onthe rotating pi e, although it permits it to slide longitudinally on thepipe ngninst the the weight, C1. y

The frame, C, it will be seen, is roughly U- shrtped in form (see Fig.10), und it is adapted to receive the pipe, A. At the forward end of thefreine are three upwerdly-projecting osts, c, forming between `them twonotcfies, in which rest the forward ends of two straps, I), D1, thesaidforward ends being held down by ineens of screws, d, pnssed through eplete, d1, secured tothe upper endsof the post, c1. Lock-nuts, (Z2, areprovided on the screws or bolts, d. The rear ends of the straps., D, D4,are passed through holes, c2, (Figs. 7, 8 and 10), in the Vupwerdly-extending rear portion of the frnme,C. The

'rear ends of these straps are likewise held down by means ofset-screws; or bolts, d8. The stfrep, D, has edjustnbly securedto it-ialguiding shoe, E, n bolt, e, serving to effect the connection, while thestra D1, cerriesfe. vshifting shoe, El, connected tierewlth by a.

bolt, ell Both these shoes beni' against the upper surface ofthe pipeend together they form the bearing which prevents downward movement ofthe freine with respect to the pipe. The shifting shoe, El, 'has otherpurposes which will presently be explained; but the shoe, E serves .onlyto furnish a large bearing conforming substantially to the sur- ,fece ofthe pipe. ends of the straps cnn be ndjusted and the shoes cen also beadjusted on the straps, so that any desired pressure can be obtainedbetween the shoes end -the pipe. When it is desired to operate on pipesof different diameters, theshoes can readily be removed` andotlierssubstituted which will conform 'to its surface. YIn ol'der tocomplete the centering of the frnmef pressure exerted by It will be seenlthat thef on lthe pipe, two other f vfrollers,

bearinglates, c4, secured thereto vThese as will be seen from Fig. 4,bear on thegfront side ofthe pipe above its center and tend to preventbackward, and, to a cerplurality of lugs, h2.

tainl extent, downward movement of thev frame on the pipe. lThe thirdbearing of the `frame on the pi e isy provided by two rollers,

G, (Figs. 4 an 7) mounted on a shaft, g,

` carried on the ends of two triangular plates,

G1, pivoted at their upper ends to the opposite sides of the rear leg ofthe frame and provided with a lock-bolt, f/l, running in slots, g2, bywhich they can be locked in any desired an lar iosition. As a furthermeans for iXing t 1e position of the rollers, G, the plates, Gr, areprovided on their lower edges withnotches, g3, (Fig. 4) which areadapted to Abe engagedby the laterally-projecting ends g, on a lockingplate, G2, (Fig. 8) adjustably secured to the rear face of the rear le.of theframe, (l. It will be seen that the rol ers, G, will cooperatewithvthe rollers,

` F, and the shoes, E, E1, to center a' pipe, of

any desired size, within the frame and will still leave the pipe free torotate within the frame while the frame is free to'slide longitudinallyon the pipe. When a pipe of srraller diameter than the one shown 1n thedrawings is used, the rollers, G, are swung up sothat the pipe may beheld at the propel height with res eet to certain forming rollshereafter deseri ed, in order that the wire may be properly ferito thepipe from said rolls.

vThe form of wire for which the machine herein illustrated isparticularly designed, is that illustrated in my pending ap lication forpatent on 'strainers for wells file December l, 1904, and allottedSerial Number 235,124.

0f the edges, 7L, of the head of the T` being plain, and the oppositeedge, h1, having a The head of the T, in practice, lies parallel to theaxis of the pipe and the central web, h3, thereof lies at right It will.be obvious that cerned could. be used with. wire of any desiredcross-section; but since, this is my .preferred wire, I illustrate amachine for operating upon it. In the use of the machine, the

wire is furnished in the-form in which it is.

wound on the ipe, except that the op osite edges of the T- iead are notfully forme until it reaches the machine. My machine, there- Tore,comprises the devices for guiding the wire, forming the flat surface andthe lugged surface on the .T-head', and windin the Wire 'upon the'ppel.These devices A' now be `with the greatest ease.

This wire indicated in the draw-A ings by, H, is T-shaped incross-section, one

scacco described, beginning at the front of the machinev where the firstguiding device which the Wire strikes is situated.

I, indicates a vertical vroller which bears against one edge of the wireas it comes from the reel, holding the same'between two vertical guiderollers, J, mounted upon a post,.j.

After the Wire passes by the rollers, J, it passes between tworollersfl, L, the said rollers having horizontal grooves, lr, Z, rc-

i of Wire bear against the ilat surface of the next turn, andconsequently the height of the lugs determines the mesh of the screen.

The liei ht of the lugs is determined exactly by the e th of thenotches,'l2, in the groove, l. In sel ing screening of this sort, it isnecessary that its mesh shall correspond approxi-A mately to the meshesof ordinary wire gauze, and by using a set of interchangeablerollers, asingle machine can. be made to turnout wire suitable for forming screenswith mesh corresponding to any of the standard gauze 'meshes In order tomake the change from one set of rollers to another a comparatively easymatter, I havey adopted the bearing herein shown which is particularlysimple and in which the rollers, K, L, can be changed It will be seenthat said rollers, K, L, are mounted on shafts, K1, L1, bein held inlace between shoulders, K2, L-, andg nuts, Ig, L3.' Bearing blocks., K",L, are provided for the shafts, K1, L, respectively. These blocks arevheld in ver- When tical guides formed between upwardly-projecting ribser flanges, c5, on the frame, C, and a plate, C, beinglaterally-adjustable by means of screws or bolts, 7c3, Z3, (Fig. 5) andivertically-adjustable by means fof screws or bolts, 7c, Z4, (Fig. 9).These blocks, it will be seen, are provided'with slightly Aflaring adjacent faces, (Fig. 5) in which faces are semicylindrical verticalgrooves adapted to receive the shafts, K1, L1. The blocks are rovidedwith central, flat-bottomed notc es, which afford space for the collarson the shait, the grooved rollers and the lock-nuts for the same. Theshoulders on the shafts lio rest against the Hat bottoms of the notchesl in the bearing blocks and revent longitudi-.-

nal movement of the ro ers with respect thereto. The device isassembled. by placing the rollers in the roper relations totheirrespective bearing locksand 'then placing the blocks in the guides.'VThe parts are then firmly locked in positionagainst any ordinarystrainwhic i couldoccurin practice.

The only motive power which is used in operating my device is thatapplied directlyr to the'pipe itself. One end of the wire is assedthrough the various guides and the orming rollsand secured to the pipe.The

I realize that considerable variation is pos sible inthe details of thisconstruction, withlBackward movement out departing from the spirit of myinvention, and I do not intend to limit myself to the s eciic formherein shown and described.

I c aim as new and desire to secure by Letters Patent 1. In a machinefor making wire wrapped strainers, the combination with means forrotating a central core upon which the wire is to be wound, of a formingdevice adapted to operate on the wire as it passes to the core, saidforming device being operated by the pull of thewire imparted by thewinding mechanism, and a shifting shoe connected to the forming deviceand arranged in such relation to the pass of the forming device as toengage the advance edge of the wire wrapped on the core'whereby theforming device is moved forward as the winding operation progresses.

2. In a machine for making wire wrapped strainers, the combination withmeans for rotating a central core upon which the wire is to be wound, ofa pair of rolls through which the wire is drawn by the pull of thewinding means in its passage to the core, and a shifting shoe connected`to the rolls and arranged in such relation to the pass between the rollsas to engage the advance edge of the wire wrapped on'tlie core, whereby-thc rolls are moved forward as the winding operation progresses.

3. In a machine for making wire wrapped strainers, the combination withmeans for ro# tating a central core upon which the wire is to be wound,of a lug-forming device comprising a pair of rolls, one of which isprovided with depressions into which the metal of the wire is compressedto form lugs, said lug-forming rolls being operated by the pull of thewire imparted by the' winding mechanism, and a` shifting shoe connectedto the forming device and arranged in such relation to the pass of theforming device as to engage the advance edge of the wire wrapped on thecore, whereby the forming device 'is moved fori` ward as the winding oeration progresses.

In witness whereof have signed the abovel a plication for Letters Patentat Jennings, in tlie. parish of (la casieu and State of Louisiana, this21st day of March, A. D. 1905.
